being combined with a housing or a staple rigid with the other hinge eye.

Y Another form of construction, subsequently described by way of example only, is mainly characterized in that use is made, as resilient locking device for two hinge eyes on the one hand, of a bevelled locking bolt rendered rigid, only angularly, with one of the hinge eyes, this locking bolt, which can move in translation, being subjected, in one direction, to the'action of a spring and, on the other hand, of a staplev rigid with the other hinge eye, this staple being provided with va slot (preferably a diametral slot) having a cross section corresponding to the V-shaped bevelled portion of the locking bolt, so that any displacement of the hinge eyes, from the locking position, lcan be effected only by exerting a sufficient stress function of the characteristics of the spring and allowing to relatively move the inclines of the staples and of the locking bolt.

The accompanying drawings illustrate, by way of example only, several forms of construction of bolt hinges according to the invention. l

` Figs. 1 and V2 are two axial sections of a Afirst form of construction of a bolt hinge.

Figs. Band 4 on the one hand, and Figs. 5 and 6 on the other hand, are two views similarto Figs. 1 and 2, of a second and third yform of construction.

Figs. 7 and 8 are an elevation and a plan view "of a buckle constituting one of the applications of the invention.

Fig. 9 is a perspective view of a watch such as above defined.

Fig. 10 is a perspective view of a clip or buckle according to the invention allowing to attach a watch on clothes.

Fig. 11 is an axial section of a fourth form of construction, the clip being closed or en tirely open. y'

Fig. 12 is a corresponding view, the clip being in the course of opening, that is to say unlocked.

In the example of construction of Figs.

U1 and 2, two sets of hinge eyes are mounted linger 9 in a longitudinal slot 10 of hinge eye 6". l

A spring 11,interposed between the ele- 'Vment 1 and the bottom of the hinge eye 3a, returns towards each other the two o-pposite ends of theelements 1 and 2 of the axis. These two ends are respectively provided with a diametral tenon 14 and with a mortice 15 which are in engagement for a relative angular position of both sets of hinge eyes (locking position). It is in fact impossible to move the two parts connected by the hinge when the two elements 1 and 2 of the axis are in engagement as shown in Fig. 1.

For unlocking, it suffices to pull outwardly a knob 12 connected, by a rod 13, to the element 1 for compressing the spring 11 and releasing the tenon 14 fromthe mortice 15. Both sets of hinge eyes are free to move and can assume for instance the relative positions they occupy in Fig. 2.

The example of Figs. 3 and 4 differs from the preceding one only in that the pull knob 12 of Figs. 1 and 2 is replaced by a push-button 12a, the rod 18"l of which passes through an axial bore of the element 2and is secured by screwing on the element 1. The spring 11 bears upon a bottom 11"L lsecured to the hinge eye by any suitable means. The same reference numbers designate like parts or parts which correspond to each other in Figs. 1 to 4. In Fig. 4, the hinge eyes, 6b and 7b have moved to the extent of 90 degrecs relatively to the position vthey occupy in Fig. 3.

ln the example of construction of Figs. 5 and 6, unlocking takes places by moving by pressure li-oth knobs 12 and 12b towards each other. The knob 12a freely ,Y passes through the element of the axis and'is secured by screwing on a slide-block 1a guided ink 35 bore 1b of the element 1 of the axis. A d1arne tral finger of the slide=block 1a passes through two longitudinal slots 1d and 10 respectively belonging to the element 1 of the axis and to the hinge eye 6b. A radial finger 16'of the element 2 is guided in a longitudinal slot y1a ensure locking when they extend into corresponding mortices 15 of the element 2. A spring 11 acts for constantly returning towards each other the opposite ends of the elements 1 and 2 and of the slide-block 1a.

. The operation is as follows:

Fig. 1 shows the locking position. If the i lingers are used for moving both knobs12a and 12b towards each other by compressing the spring 11, the elements 1 and 2 and the slide-block 1a are brought in the positions they occupy in Fig. 7,'the tenons 14 are released from the mortices 15, and the locking is obtained. e

The passage from the locking to the unlocking positions can be examined .according to two successive conditions: y f

'i (1) By acting on the knob 12a, the elements l and 2 remain stationary, the slide-block 1a iso vce

is moved towards the left according to a distance V d l being the depth of engagement of the ten# ons 14 into the mortices 15. y f

(2) By acting on the knob 12b, whilst the knob 12L and the slide-block 1a are held sta-rV and 6. The plate 17 is provided on its inner Vface with points 19 theends of which, in closing position, can enter perforations on the plate 18. lVhen both plates are moved towards each other by clamping between them the fabric of a garment (lapel of a coat for p y'1t 1s necessary for opening it to eXert a suflicient stress on the jaws for overcoming the ,reaction of the spring 26. The action of the"v instance) and the end of a ribbon or 'of a chain as explainedv above, the hinge is locked, it can be unlocked only by simultaneously pressing on the knobs 12aand 12b.

Fig. 9 illustrates a watch on the case of which Iare secured hinge eyes connected by a bolt hinge, constructed for instance as shown in Figs. 5 and 6, to a small plate 2() capable of receiving any desired decoration. This plate 2O provided with points such as the points 19 of Figs. 7 and 8, allows oi securing the watch in a coat pocket, or on the Wrist band of a sleeve. Thus secured, the watch cannot accidentally unfasten itself.

The buckle illustrated in Figs. 10, 11 and 12 comprises two groups of hinge eyes mounted on one and the same axis composed of two r elements 1 and 2. The hinge eyes 17a and 17 b jaw 17 of the clip, and the J I y I What I A-t'o secure by Letters Patent, VAis:

belong to the hinge eye 18a is rigid with the Vjaw 18.

The hinge eye 17a is permanently secured by a diametral screw 9 on the said element 2, whilst the hinge eye 18EL is rendered rigid by a screw 16, with the element 1. The latter is loosely mounted in the hinge eyes 17L of the width of the hinge eye 17afor allowing the and 17b and occupies only a portion element 2 to take a bearing thereon.

The element 1 is angularly connected, in to the element 2 forming a' locking position, kerf at 23, by a locking bolt 22 extending in the kern 23.

The bevelled locking bolt 22has a rectangular cross-section. responding diametral recess 22a of the element 1 and is terminated by a spindle 24 moving in an axial recess 24a of the same element 1. This spindle 24 extends in a recess 25 the latter.

It slides in a cor-y :P

vof :larger Vdiameterinfwhich a returning Vspring 26' is arranged. This spring bears, on the one hand, Ywithinterposition of a steel washeror the like, on the end'wall of vthe vvhinge eye '17". which forms a cap and,fon thev other hand, on the spindle 24'of` the locking `=bolt 22 through the medium of a Awasher 27.

v"The kerl 23, lcorresponding to the bevelled endof the locking bolt 22, forms inclines, so

that when the locking'bolt is angularly driven by the user acting onv the jaws of the clip,it

moves angularly'and in translation for com ing to the position shown in Fig. 12. An end piece or member l 28, preferably of` `precious metal as thelhinge eyesY and jaws, is provided tral. screw 8 for securing 'the element 2 to the hinge eye 17 -,passes'through the spindle 28a'ofits end member' 28, thus renderingit Yrigid with the whole.

The operation ofthe locking Ydevice illustrate'd in Figs. 10, 11 and 12 isV as rfollows:

The clip or hinge being closed and locked,

inclines of the kerf 23 on the bevelled portranslationv of the latter which, angularly connected to the jaw 1.7, is angularly driven with After. a sufficient angular dis# pla'eementits end rests on 'the plane end portions of the element 2. When theclip 1 is opened through an angleof 1800, the locking bolt 22 again enters the kerf 23- andlocks -Y the-clip'in the open position.

-Asin the forms of construction'illustrated with a spindle28a entering an axialibore 29 of theelement 2. The latter can convenientlyy be made of a hard metal such as' steel, for

avoiding thedistortion of the lockingbolt 22 or of the inclines of the kerf 23.4 The diamein Figs. 1 to 9, one of the jawsv orzboth'are provided, onv their v.inner face,with kpoints 19 the ends ofl-which, in closed position, can enter perforations of the opposite small plate or 21W; i
